Parascytoleptus papua Poore and Collins, 2010:614–618 , figs 1,2.

Material examined. Papua New Guinea. Madang Province, PAPUA NIUGINI stations. N of Riwo mangrove and seagrass, 05°08.7'S, 145°48.2'E, 2 m (stn PB48 ), IU-2013-7100 (male, 2.6 mm). N of Sek I., inner slope, 05°04.7'S, 145°48.9'E, 3 m (stn PB50 ), NMV J71642 (2 males, 2.8, 3.1 mm) .

New Ireland Province, Kavieng region , KAVIENG 2014 station. NW side of Ral I., coral wall, 19 m, 02° 36.4' S, 150° 42.4' E (stn KB62), IU-2014-2735 (female, 3.0 mm); IU-2014-17694 (male, 3.6 mm) .

Distribution. Papua New Guinea, Madang and New Ireland provinces; 2–19 m depth.

Remarks. The types were collected not far from the new material. The major cheliped of the adult male figured here is longer and more elongate than that of the female figured by Poore and Collins (2010). Sakai (2011) diagnosed the genus with the male pleopod 1 ‘a small unsegmented protrusion’ based on its presence on two males of 4.2 mm and 5.3 mm length. This has not been observed on the holotype of P. papua (4.2 mm) or the smaller males reported here. The pleopod 1 may appear only in larger specimens.
